Features and Overview
 

  • Industry standard Philips I2C bus compatible interface
  • Slave only operation
  • Only two pins (SDA and SCL) required to interface to I2C bus
  • Standard data rate of 100/400 kbits/s, also supports 50 kbits/s
  • High level API requires minimal user programming
  • 7-bit addressing mode
     

The I2C Hardware User Module implements an I2C Slave device in firmware. The I2C bus is an industry standard, two wire hardware interface developed by Philips®. The master initiates all communication on the I2C bus and supplies the clock for all slave devices. The I2CHW User Module supports the standard mode with speeds up to 400 kbits/s and is compatible with other slave devices on the same bus.
